Ok, I must have been in the wrong section in the FSM, I saw 28-32. It's been many years since I have messed with points!

But, if I isolate EITHER set of points, it runs great. Bring the other set in, and all the issues.

So is a total dwell of 32 enough to cause this issue? doesn't seem like it to me...


I would reset both sets. I had a old Accel dual point and as soon as the rubbing block wore the points would stay closed to long and the car ran poorly. On a lot of performance dual points the point sets have a lot of spring tension so the blocks wear. Make sure you are using lobe lube. If it were me I would set them with a feeler gauge and recheck the timing.
